Errors with my punch script

[dodo64bit (d64b)]

A few days ago I tried to script the animations using the tutorial on the internet and the animation didn’t work. Today I tried from scratch to try to program a script for punching. I ran into a problem again where the animation doesn’t start and I get errors. I checked if I have everything in the right place and I looked at a few Developer Hub topics that mention the punching script, I checked their code and it seemed like I did everything right.

Here is my code and the errors I am getting and also where my script and animation is located.

• location
  
• code

local player = game.Players.LocalPlayer
local character = player.Character

local UIS = game:GetService("UserInputService")
local mouse = player:GetMouse()

local animation = script.Animation

UIS.InputBegan:Connect(function(input)
	
	local humanoid = character:WaitForChild("Humanoid")
	
	if input.UserInputType == Enum.UserInputType.MouseButton1 then
		local animationTrack = humanoid:WaitForChild("Animator"):LoadAnimation(animation)
		animationTrack:Play()
	end
	
end)

• error

Animation is not a valid member of LocalScript “Workspace.dodo64bit.LocalScript”

Never mind, I fixed it. It seems that the animation, even if it is already a child of the script, I still have to put the :WaitForChild() function.

But I’m still curious, why the :WaitForChild() function, why not just animation = script.Animation?

WaitForChild() basically yields your script (stops it) until the child your are waiting for is done loading.
